我希望按钮本身在线时(基于互联网连接)更改为绿色,否则为灰色.

我有一个JS小提琴,它提供了一个单击按钮的解决方案,我们可以通过警报查看我们是否在线/离线.

有人可以请帮助

HTML:

<div data-role="page" id="index">
  <div data-theme="a" data-role="header">
    <h3>First Page</h3> <a href="#second" class="ui-btn-right">Next</a> </div>
  <div data-role="content"> <a data-role="button" id="check-connection">Check internet connection</a> </div>
</div>

jQuery的:

$(document).on('pagebeforeshow', '#index', function() {
  $(document).on('click', '#check-connection', function() {
    var status = navigator.onLine ? 'online' : 'offline';
    (alert(status));
  });
});

见JSFiddle.

我有以下要求获取注册表格来发布数据.但是我无法测试它,有人可以帮忙.我想看看数据是否正在传递？我有jquery cdn和jquery-validate.

我有那个傻瓜

jQuery的:

// Code goes here

$(function() {

    /* Registration form for the website */
    /* validation */
    $("#register-form").validate({
        rules: {
            firstName: {
                required: true
            },
            lastName: {
                required: true
            },
            userName: {
                required: true,
                minlength: 4
            },
            email: {
                required: true,
                email: true
            },
            password: {
                required: true,
                minlength: 8,
                maxlength: 15
            },
